Hot selling MS5803-05BA Micro Air Pressure Sensor Brand New Original Product Quality Assurance

Product Descriptions

The MS5803-05BA is a new generation of high resolution altimeter sensors from TE Connectivity with SPI and I2C bus interface. It is optimized 

for depth meters and altimeters with an altitude resolution of 30 cm. The sensor module includes a high linearity pressure sensor and an ultra-

low power 24 bit ΔΣ ADC with internal factory calibrated coefficients. It provides a precise digital 24 Bit pressure and temperature value and 

different operation modes that allow the user to optimize for conversion speed and current consumption. A high resolution temperature output 

allows the implementation of an altimeter/thermometer function without any additional sensor. 

The MS5803-05BA can be interfaced to virtually any microcontroller. The communication protocol is simple, without the need of programming 

internal registers in the device. The gel protection and antimagnetic stainless steel cap allows the use in 100m waterproof watches. 

This new sensor module generation is based on leading MEMS technology and latest benefits from TE proven experience and know-how in 

high volume manufacturing of altimeter modules, which have been widely used for over a decade. The sensing principle employed leads to very 

low hysteresis and high stability of both pressure and temperature signal.
